Imboni Yokukhiqiza Izimoto zikagesi, iqondisa ukukhiqizwa nokugqugquzelwa kwemishini yokonga amandla kagesi (imikhiqizo), ihlanganise umsebenzi wangempela wokonga ugesi nowokunciphisa ukungcola kwemboni yezokuxhumana, futhi inconywe, ukubuyekezwa kochwepheshe kanye nokwaziswa yiminyango enekhono. yezimboni kanye nobuchwepheshe bolwazi kanye nezimboni ezihlobene ezindaweni ezahlukene.Ikhathalogi ihlanganisa ingqikithi yamamodeli angama-344 ezigabeni eziyi-9.Phakathi kwabo, transformers 96 onobuhle, motors kagesi onobuhle 59, boilers ezimbonini 21 onobuhle, Welding imishini 77 onobuhle, esiqandisini onobuhle 43, compressors 27 onobuhle imikhiqizo, umshini plastic 5 onobuhle, fan 13 onobuhle, ukushisa 3 onobuhle.

Uhla lwemibhalo lusebenza iminyaka emithathu kusukela ngosuku olushicilelwe ngalo.Ngesikhathi sokuqinisekisa, uma kukhona ukuqanjwa okusha kubuchwepheshe bomkhiqizo kanye noshintsho olukhulu kumazinga okuhlola, inkampani izophinde imemezele.^[2]

Izinyathelo zokuzivikela

Hlela Izwi

(1) Ngaphambi kokususwa, phephetha uthuli ebusweni benjini ngomoya ocindezelwe bese usula ukungcola okungaphezulu kuhlanzekile.

(2) Khetha indawo lapho injini ihlakazeka khona futhi uhlanze indawo yasensimini.

(3) Yazi izici zesakhiwo semoto kanye nezidingo zobuchwepheshe zokulungiswa.

(4) Lungiselela amathuluzi (kuhlanganise namathuluzi akhethekile) nezinto ezidingekayo ukuze kuhlakazwe.

(5) Ukuze kuqondwe kabanzi amaphutha ekusebenzeni kwemoto, ukuhlolwa kokuhlola kungenziwa ngaphambi kokususwa lapho izimo zikhona.Kuze kube manje, injini izoba ukuhlolwa komthwalo, ukuhlolwa okuningiliziwe kwezingxenye zemoto zezinga lokushisa, umsindo, ukudlidliza nezinye izimo, kanye ne-voltage yokuhlola, yamanje, isivinini, njll. test, kukala ukulahlekelwa kwamanje okungenalutho kanye nomthwalo ongenalutho, yenza irekhodi elihle.

(6) Nqamula ugesi, susa izintambo zangaphandle zenjini, futhi wenze irekhodi elihle.

(7) Hlola ukumelana nokufakwa kwezimoto ngemitha ye-meE enevoltheji elungile.Ukuze uqhathanise amanani okumelana nokufakwa kwe-insulation akalwe enkonzweni yokugcina ukuze kutholwe amathrendi e-insulation ye-motor kanye nesimo sokugquma, amanani okumelana nokufakwa kukalwa kumazinga okushisa ahlukene kufanele aguqulelwe kuzinga lokushisa elifanayo, ngokuvamile libe ngu-75degrees C.

(8) Isilinganiso sokuhlola sokumuncwa K. Uma isilinganiso sokumuncwa sisikhulu kuno-1.33, ukushunqiswa kwemoto akumanzi noma akuswakanyiswa kakhulu.Ukuze kuqhathaniswe nedatha yangaphambilini, isilinganiso sokumuncwa esikalwa kunoma yiliphi izinga lokushisa siphinde siguqulelwe kuzinga lokushisa elifanayo.
